  • Patent number: 10518611
    Abstract: Provided is a power slide window which can synchronize the winding and unwinding movements of the upper drive cables and the lower drive cables, and can be assembled with ease. The power slide window (1) includes an upper drive cable (10U) connected to an upper part of the slide panel and extending from the slide panel in a lateral direction along a surface of the window glass pane, a lower drive cable (10D) connected to a lower part of the slide panel and extending from the slide panel in the lateral direction along the surface of the window glass pane, a first pulley (40) configured to be rotatably driven by the drive source to wind and unwind the upper drive cable, a second pulley (50) configured to be rotatably driven by the drive source to wind and unwind the lower drive cable, and a coupling structure (60) provided between the first pulley and the second pulley to allow the first pulley and the second pulley to be joined to each other at a selected relative angular relationship.

  • Patent number: 10434845
    Abstract: An opening formed in a window glass pane is smoothly opened and closed by a slide panel slidingly driven along a panel surface of the window glass pane and along a direction orthogonal to the panel surface. The guide rail (4) is provided with a pin guide groove (27) including a groove main portion (27a) and a groove extension portion (27b). A slider (20) is provided with a pin drive groove (30) extending in a direction crossing the panel surface. The slide panel is provided with at least one pin (16) projecting into the pin drive groove and the pin guide groove so that the slide panel is positioned in a closed position when the pin is positioned in the groove extension portion, and in an open position when the pin is positioned in the groove main portion.
